Configuration
The Tracer AH540/541 controller is factory configured and commissioned
with fixed sequences of operation. All of the controller configuration
parameters are predefined and loaded based upon the air-handling unit
configuration. The Rover service tool provides access to these parameters
to make adjustments to the controller operation. (Refer to the Rover Oper-
ation and Programming guide, EMTX-SVX01E-EN, for more informa-
tion.)
Use the Rover service tool to configure the Tracer AH540/541 controller.
You can configure each of the inputs as normally open or normally closed.
Configure inputs or outputs that are not in use (one to which no device is
physically connected) as Not Used. This will disable the generation of
diagnostics for this function.
The Tracer AH540/541 contains configuration parameters for selecting
the control mode of the air-handling unit, heating and cooling source,
face-and-bypass damper, and outdoor air damper. The desired air-handler
operation determines the valid temperature control options: space tem-
perature control or discharge air temperature control. See Table 28
through Table 48.
